flagman

The division engineer, with his front flagman, had already galloped half a mile away across the plain.

He has also made some changes in his force, and is going to see what sort of a front flagman Glen Eddy will make.

Three shrill whistle calls sent a sleepy flagman racing to set the switch of the siding.

Heres a handful, my hearty, and the flagman darted into the little shanty and out again with a fistful of great chunks of chalk.

The flagman on the end of the train had helped the boy aboard the last car as the train started to move.
